Dark brown; integument smooth. 



Cephalothorax one half as long as high; dorsal surface 

 with two pairs of bristles, — a very long, almost straight pair, 

 three fourths as long as the cephalothorax itself, situated near 

 the posterior border, and a small, curved pair near the tip. 

 Pseudostigmata round, situated at the posterolateral extrem- 

 ity of the cephalothorax; pseudostigmatic organ slightly re- 

 curved. 



Abdomen subglobose; upper half of the anterior margin 

 concave, lower half straight ; ventral margin moderately 

 convex; dorsum with two rows of submedian bristles, six bris- 

 tles in each row. (lenito-anal covers almost completely con- 

 cealed when viewed from the side, the anterior corner, however, 

 visible as a triangular chitinous projection. 



Anterior pair of legs stouter than the other pairs, which 

 are subequaJ. Tarsus of leg I nearly twice as long as the 

 tibia; tibia slightly longer than the genual; femur longer than 

 the tibia and genual combined. Claws slightly more than 

 half as long as the tarsi from which they extend. All the legs 

 are sparsely clothed with rather long, simple bristles.
